Analysis of Alum‚ AlK(SO₄)₂ •12H₂O Purpose The purpose of the experiment is to confirm whether the compound is Alum. Introduction Percent composition is defined as part divided by whole multiplied by 100. Water of hydrogen is defined as the amount of water produced into a molecule prepared in an aqueous solution. Molecular formula indicates the actual numbers and type of atoms in a molecule (notes). Procedure The procedure in this experiment is to determine melting point and mole ratio of

The Formation of Alum Crystals from Solutions in Two Different Thermal Conditions Burce P.J.‚ Cachuela J.A.A.‚ Capistrano M.M. I. Objectives The experiment aims to describe crystals and its aggregates by creating crystals of Alum (AlK (SO4)2 ∙12H2O)‚ commonly known as Tawas‚ from solution. Two setups will be created; crystals from each setup will be allowed to form at two different thermal conditions. With this‚ the experiment also aims to describe how temperature affects the formation of

Analysis of Alum The objective of this lab is to run tests on a compound and analyze the substance itself‚ and then determine whether or not the compound is actually alum. Jill Cline Period 3 November 19‚ 2013 Laurel Hergenroeder and Sarinah Martelli Introduction/Purpose The purpose of this experiment is to run various tests on the substance called alum. (AlK(SO4)2 ∙ 12H2O). These tests like the process of filtration heating the solution will reveal things

acidic. The pH were dropped because when the alum dissolved in water‚ aluminium‚ sulphate and hydrogen ions were released. At time of precipitation of Al(OH)3‚ there were only two types ions remained in solution which were hydrogen and sulphate ions. To such a degree‚ effectively‚ the addition of alum and the precipitation of Al(OH)3

separate procedures in which Aluminum Potassium Sulfate(Alum) will be melted‚ massed out and mixed with Barium Nitrate‚ along with distilled Water. Procedure one we completed two trials of melting two separate 0.01g of Alum and making a comparison to the literature temperature of 92.5‚ to do this we attached an Alum filled capillary tube to a thermometer and inside a beaker placed over a Bunsen burner. Procedure two consisted of placing 2.00 grams of Alum into a crucible and heating it over a Bunsen burner

molar components in alum. This was conducted by heating the alum till the water had evaporated and then determining the number of moles for each component. Then using the these amounts to figure out the empirical formula for alum. Results: In order to determine how much of each separate component a total mass was taken before hand for both the aluminum cup and the alum. These weights were shown to be 4.5g for the aluminum cup and 2.0g for the alum crystals. Once the alum was placed over the heat

It’s not just affordable; it’s also safe and non-toxic because the ingredients used are starch‚ water‚ natural dyes from plants and alum. Alum is used as preservative to prolong the shelf-life of the paste. Natural dyes from plants like Annatto seeds‚ mayana and turmeric were tested as coloring for this paste. We can also use other coloring from plants by researching and do further study
